Imagine you are sitting under the shade of an Acacia tree, enjoying the beauty of the African savanna landscape. Suddenly you spot a small, hard ball of poop rolling along the ground, apparently of its own volition! Take a step closer, and you might catch a glimpse of one of the most important creatures in the savanna ecosystem – the dung beetle.

More than 100 species of dung beetle have been recorded in Serengeti National Park alone, with different strategies in how they utilize the dung. “Roller” beetles create a ball of dung up to 40 times their body weight and can transport it up to 70 meters away, thus spreading nutrients far and wide. “Tunneller” beetles bury their balls of dung, helping the plant seeds within to germinate. Without these beetles, the ground would quickly be covered in a thick layer of dung, smothering the grasses that ungulates depend on for food.

Even the lowliest members of an ecosystem play critical roles in the intricate web of life.
